A group of entrepreneurs and businessmen from Iowa commissioned this painting from Grant Wood. They intended to present it to the sitting president, Herbert Hoover. The president was born in a white frame cabin in West Branch, Iowa. Grant Wood made a point of representing the birthplace as accurately as possible. However, President Herbert Hoover did not think he did it justice. He refused to accept the painting because it included a larger house obscured the small cabin where he was born. In other words, the cabin was not the focus of the painting and did not stand out. During his campaigns, he had emphasized his humble origins, and according to him, the piece did not paint an accurate picture.
